- E-Sens's "Flight"

After giving some of the songs above a listen, netizens also shared their thoughts with comments like:

"A lot of these songs are more hip-hop."

"BoA's 'Christmas Paradise'!! I remember listening to that song a lot because I liked it so much."

"I always thought BoA's 'Christmas Paradise' had a unique beat."

"[250] worked on a lot of E-Sens songs, and some of them have similar background vibes to NewJeans songs."

"'Flight'?? Even among hip-hop fans, that song is like a 'life song' for so many people."
